Explanation:

For proofs of this nature, it often works well to replace everything possible with appropriate equivalents. Here, we'll use sin² to represent sin²(A), and equivalent notation for other trig functions.

We will change the left side to the form of the right side.

  [tex]\displaystyle \frac{\tan^2-\cot^2}{1+\cot^2}=\frac{\sin^2-\cos^2}{\cos^2}\\\\=\frac{(\sec^2-1)-(\csc^2-1)}{\csc^2}\\\\=(\sin^2)(\sec^2-\csc^2)\\\\=\frac{\sin^2}{\cos^2}-1=\frac{\sin^2-\cos^2}{\cos^2}\qquad\text{Q.E.D.}[/tex]

__

The equivalents (identities) used are ...

  1+tan² = sec²

  1+cot² = csc²

  1/csc = sin

  sec = 1/cos

Answer:

2.8 liters

She drank 2.8 liters all together.

Step-by-step explanation:

0.878+1.2+0.75= 2.8

Nicky drank a total of 2.828 liters of water throughout the day.

To find out how much water Nicky drank altogether, you can add up the amounts of water she drank throughout the day.

0.878 liters after breakfast.

1.2 liters after lunch.

0.75 liters before dinner

Adding these values together:

0.878 + 1.2 + 0.75 = 2.828

Therefore, Nicky drank a total of 2.828 liters of water throughout the day.

Answer:

For this expression:

            a=15  , b=7 and c=4

Step-by-step explanation:

We are asked to find the value of a,b and c by representing the given expression:

in the form of:  

where a is the base and b is the numerator of the exponent and c is the denominator of the exponent.

We know that the expression of the type:

is also written as:

Hence, we get our expression as:

Answer: 42 degrees

Step-by-step explanation: sum of angles in triangle is 180 degrees.

So third angle is 180-44-94= 42

Answer: 42°

Steps:

44° + 94° + x = 180°

138° + x = 180°

x = 180° - 138°

x = 42°

Check:

44° + 94° + 42° = 180°

180° = 180° ✅

Answer:

7

Step-by-step explanation:

you divide 56 by 8 and you get 7

Width of the field is 7 yards

Given that;

Area of soccer field = 56 square yard

Length of one side = 8 yards

Find:

Width of the field

Computation:

Area of soccer field = Area of rectangle

So,

Area of soccer field = [Length of one side][Width of the field]

56 = [8][Width of the field]

Width of the field = 56 / 8

Width of the field = 7 yards

square them, then add them and square root them.

Answer:

22 hens and 78 sheep

Step-by-step explanation:

Let the number of hens = x

Number of sheep = y

Total heads = 100

x +  y = 100      --------------------(I)

 x = 100 - y

Number of legs of 'x' hen = 2*x = 2x

Number of legs of 'y' sheep = 4*y = 4y

total legs = 356

2x + 4y =  356 -----------------------(II)

Substitute x = 100 -y in equation (II)

2(100 - y) + 4y = 356

2*100 - 2*y + 4y = 356

200 - 2y + 4y    = 356 {Combine like terms}

        200  + 2y = 356          {Subtract 200 from both sides}

                   2y = 356 - 200

                  2y = 156       {Divide both sides by 2}

                    y = 156/2

                  y = 78

Plugin  y = 78 in equation (I)

x + 78 = 100

       x = 100 - 78

       x = 22

22 hens and 78 sheep

Answer:

ok, so, since the angles in a traingle all sum up to 180°, that would make:

36°+61°+(4x-17)°=180°

We simplify it:

95°+(4x-17)°=180°

Then, we subtract 95° on both sides:

95°+(4x-17)°=180°

-95°               -95°

Then we get:

4x-17°=85

We add 17° on both sides

4x-17°=85

   +17°  +17°

And we get:

4x=102°

Divide 4 on both sides...

4x=102°

The correct question is:

[tex]\angle QPS=88[/tex]  

[tex]\angle RPS=5x+34[/tex]

[tex]\angle QPR=8x+15[/tex].

Find ∠QPR.

Answer:

[tex]\angle QPR = 39[/tex]

Step-by-step explanation:

From the attached figure:

[tex]QPS = QPR + RPS[/tex]

This gives:

[tex]88 = 8x + 15 + 5x + 34[/tex]

Collect like terms

[tex]88 - 15 - 34 = 8x + 5x[/tex]

[tex]39 = 13x[/tex]

Divide both sides by 13

[tex]3 = x[/tex]

[tex]x =3[/tex]

Substitute [tex]x =3[/tex] in [tex]\angle QPR=8x+15[/tex]  

[tex]\angle QPR = 8 * 3 + 15[/tex]

[tex]\angle QPR = 24 + 15[/tex]

[tex]\angle QPR = 39[/tex]
